I'm going to throw out the weight you would be hauling at 8000 to 9000 lbs.  That probably means a 14k trailer.  If I was hauling that a lot or long distances, I'd want a gooseneck.  If not a bumper pull would probably be fine.  I'd count on the load your hauling plus the trailer being at least 11,000 lbs and maybe more like 12,000 lbs.  I haven't looked up the actual capacity of your truck, but I bet thats more than you should be pulling.  That said, a good hitch, a weight distributing hitch with sway control, you would be safer than some of the stuff you see going down the road.
